Fundamentals of Infrared (IR) Technology

Fundamentals of Infrared (IR) Technology  provides a basic understanding of the physical background and engineering considerations required for the design of IR systems, examining all components and combining them into imaging, sensor and surveillance systems. Participants will learn about state-of-the-art optical systems, lightweight mirrors and adaptive optics, planar-hybrid and Z-technology focal planes, design of a ground-based IR astronomical telescope,  laser-radar systems.

Infrared (IR) thermal imaging, thermography, IR detector design, electronics, and computer science. Topics such IR radiation, radiometry, blackbody radiation, emissivity and optical material properties in IR.

Blackbody Radiation and basic laws reveals the quantitative changes of infrared thermal radiation in relation to temperature and wavelength.  Concretely speaking, the following four basic laws can be generalized:

  • Spectrum distribution law of radiation—Planck’s radiation law
  • Movement law of the radiation spectrum—Wien’s displacement law
  • Law of change of radiation power with changing temperature—Stefan–Boltzmann law
  • Spatial distribution law of radiation—Lambert’s cosine law.

Target Audience:

The intended audience for this training are professionals who want to know more about  Infrared technology and system. Engineers, scientists, testers, system engineers and managers interested in procedures, methods, applications and techniques associated with  infrared , sensor system analysis design, testing, evaluation and analysis.
